Spiral Duct Grilles

Airvector®’s GDA and GDS Series of Spiral Duct Grilles were designed with aesthetics in mind as well as time-saving properties to allow for quick installation; the curved extruded frame and fins which both precisely follow the curve of the spiral duct propose straightforward plug-and-play.

Series GDA and GDS are designed for spiral duct installation in commercial open-ceiling applications and are recommended for supplying heated, ventilated or cooled air.

Airvector® Spiral Duct Grilles are fabricated with a curved extruded aluminum frame and adjustable roll-formed fins that follow the face’s curve. Can be provided with an air scoop or an opposed blade damper to adjust the air pattern. Available with powder coated colors and finishes.
